■ How to identify the series of Throttle (Needle) Valve and Speed Controller

Detailed Safety InstructionsBefore using PISCO products, be sure to read “Safety Instructions” and “Safety Instruction Manual” and “Common Safety Instructions for Controllers”.

Warning1. When controlling the speed of actuators, slowly release the air by adjusting the needle

from a fully closed state. In case the needle is opened, actuator can move suddenly.Turn needle in the clockwise direction to close, and in the counterclockwise to open.

2. Do not swing or rotate resin body of the products by force. It may damage to theproducts and cause a fluid leakage.

3. Resin can be deteriorated by being exposed to direct sunlight or ultraviolet rays.

Caution1. Throttle (Needle) valve permits some air leakage. Do not use the products for the

application which requires no leakage.2. The seal rubber material EPDM is not suitable for general air piping, due to its inferior

durability against mineral oil.3. Taper thread is not coated by Sealock. When coating the thread with seal tape or

sealant, do not coat 1.5 to 2 screw ridges from the tip of the thread.4. If there is a possibility of fire by a fluid leakage, implement specific countermeasures such

as using a protective cover in order to protect machines / facilities from damages or fire.5. Tube insertion into Throttle (Needle) Valve PP Series is tighter than that of Throttle

(Needle) Valves due to its oil-free specification. Make sure to insert tube up to tubeend. When inserting a tube, put a liquid like water on the tube, which does not affect theproduct and the tube. It will improve the smoothness of tube insertion.

■ How to adjust the speed1. Speed adjustment of actuators

① Increasing speed Tu r n t h e n e e d l e i nthe counterc lockwised i rec t ion f rom a fu l lyclosed state. The morethe needle is opened, thefaster the actuator moves. Make sure to tighten thelocknut at the desiredspeed. The speed settingcan be changed withouttightening the locknut.

■ How to insert and disconnect1. How to insert and disconnect tubes

① Tube insertion

Insert a tube into Push-In Fitting up to the tube end. Lock-claws bite the tube

and fix it automatically, then the elastic sleeve seals around the tube.

Refer to “2. Instructions for Tube Insertion” under “Common Safety Instructions

for Fittings” .

② Tube disconnection

The tube is disconnected by pushing release-ring to release Lock-claws.

Make sure to stop air supply before the tube disconnection.

2. How to tighten thread① Tightening thread

Use a spanner to tighten a hexagonal-column.

① Beyond the specifications or conditions stated in the catalog, or the instructions.② Under the direct sunlight or outdoors.③ Excessive vibrations and impacts.④ Exposure / adhere to corrosive gas, inflammable gas, chemicals, seawater, water and vapor. *

＊ Some products can be used under the condition above(④), refer tothe details of specification and condition of each product.

2. Do not disassemble or modify PISCO products, which affect theperformance, function, and basic structure of the product.

3. Turn off the power supply, stop the air supply to PISCO products, and make surethere is no residual air pressure in the pipes before maintenance and inspection.

4. Do not touch the release-ring of push-in fitting when there is a working pressure.The lock may be released by the physical contact, and tube may fly out or slip out.

5. Frequent switchover of compressed air may generate heat, and there is arisk of causing burn injury.

6. Avoid any load on PISCO products, such as a tensile strength, twistingand bending. Otherwise, there is a risk of causing damage to the products.

7. As for applications where threads or tubes swing / rotate, use RotaryJoints, High Rotary Joints or Multi-Circuit Rotary Block only. The otherPISCO products can be damaged in these applications.

8. Use only Die Temperature Control Fitting Series, Tube Fitting Stainless SUS316Series, Tube Fitting Stainless SUS316 Compression Fitting Series or Tube FittingBrass Series under the condition of over 60℃ (140°F) water or thermal oil. OtherPISCO products can be damaged by heat and hydrolysis under the condition above.

9. As for the condition required to dissipate static electricity or provide an antistaticperformance, use EG series fitting and antistatic products only, and do not use other PISCOproducts. There is a risk that static electricity can cause system defects or failures.

10. Use only Fittings with a characteristic of spatter-proof such as Anti-spatter or Brass series in a place where flame and weld spatter isproduced. There is a risk of causing fire by sparks.

11. Turn off the power supply to PISCO products, and make sure there isno residual air pressure in the pipes and equipment before maintenance.Follow the instructions below in order to ensure safety.① Make sure the safety of all systems related to PISCO products before maintenance.② Restart of operation after maintenance shall be proceeded with care after

ensuring safety of the system by preventive measures against unexpectedmovements of machines and devices where pneumatic equipment is used.

③ Keep enough space for maintenance when designing a circuit.12. Take safety measures such as providing a protection cover if there is a

risk of causing damages or fires on machine / facilities by a fluid leakage.

PISCO products are designed and manufactured for use in general industrial machines. Be sure to read and follow the instructions below.

Caution1. Remove dusts or drain before piping. They may get into the peripheral

machine / facilities and cause malfunction.2. When inserting an ultra-soft tube into push-in fitting, make sure to place

an Insert Ring into the tube edge. There is a risk of causing the escape oftube and a fluid leakage without using an Insert Ring.

3. The product incorporating NBR as seal rubber material has a risk ofmalfunction caused by ozone crack. Ozone exists in high concentrationsin static elimination air, clean-room, and near the high-voltage motors,etc. As a countermeasure, material change from NBR to HNBR or FKM isnecessary. Consult with PISCO for more information.

4. Special option “Oil-free” products may cause a very small amount of a fluidleakage. When a fluid medium is liquid or the products are required to beused in harsh environments, contact us for further information.

5. In case of using non-PISCO brand tubes, make sure the tolerance of theouter tube diameter is within the limits of Table 1.●Table 1. Tube O.D. Tolerance

mm size Nylon tube Polyurethane tube inch size Nylon tube Polyurethane tubeø1.8mm ─ ±0.05mm ø1/8 ±0.1mm ±0.15mmø3mm ─ ±0.15mm ø5/32 ±0.1mm ±0.15mmø4mm ±0.1mm ±0.15mm ø3/16 ±0.1mm ±0.15mmø6mm ±0.1mm ±0.15mm ø1/4 ±0.1mm ±0.15mmø8mm ±0.1mm ±0.15mm ø5/16 ±0.1mm ±0.15mmø10mm ±0.1mm ±0.15mm ø3/8 ±0.1mm ±0.15mmø12mm ±0.1mm ±0.15mm ø1/2 ±0.1mm ±0.15mmø16mm ±0.1mm ±0.15mm ø5/8 ±0.1mm ±0.15mm

6. Instructions for Tube Insertion① Make sure that the cut end surface of the tube is at right angle without

a scratch on the surface and deformations.② When inserting a tube, the tube needs to be inserted fully into the push-

in fitting until the tubing edge touches the tube end of the fitting asshown in the figure below. Otherwise, there is a risk of leakage.

Tube end

Sealing

Tube is not fully inserted up to tube end.

③ After inserting the tube, make sure it is inserted properly and not to bedisconnected by pulling it moderately.

※. When inserting tubes, Lock-claws may be hardly visible in the hole, observedfrom the front face of the release-ring. But it does not mean the tube willsurely escape. Major causes of the tube escape are the followings;①Shear drop of the lock-claws edge②The problem of tube diameter (usually small)Therefore, follow the above instructions from ① to ③, even lock-clawsis hardly visible.

Good Imcomplete

7. Instructions for Tube Disconnection① Make sure there is no air pressure inside of the tube, before disconnecting it.② Push the release-ring of the push-in fitting evenly and deeply enough to

pull out the tube toward oneself. By insufficient pushing of the release-ring, the tube may not be pulled out or damaged by scratch, and tubeshavings may remain inside of the fitting, which may cause the leakagelater.

8. Instructions for Installing a fitting① When installing a fitting, use proper tools to tighten a hexagonal-column

or an inner hexagonal socket. When inserting a hex key into the innerhexagonal socket of the fitting, be careful so that the tool does nottouch lock-claws. The deformation of lock-claws may result in a poorperformance of systems or an escape of the tube.

② Refer to Table 2 which shows the recommended tightening torque. Donot exceed these limits to tighten a thread. Excessive tightening maybreak the thread part or deform the gasket and cause a fluid leakage.Tightening thread with tightening torque lower than these limits maycause a loosened thread or a fluid leakage.

③ Adjust the tube direction while tightening thread within these limits,since some PISCO products are not rotatable after the installation.

Before selecting or using PISCO products, read the following instructions. Read the detailed instructions for individual series as well as the instructions below.

1. Some products have an air direction to control. Make sure to distinguish thedirection by marking on the products. Installing the product with the wrongdirection may cause personal injury or property damage.

2. Avoid any load on PISCO products such as a tensile strength, twisting,bending, dropping and excessive impacts. These may cause damage to theproducts.

3. Locknut needs to be tightened by hand. Do not use any tool. Using tools totighten the locknut may cause damage to the products. Also, inadequatetightening may loosen the locknut and the initial setting can be changed.

4. Use clean air to supply. Dusts and sludge may result in the change of theinitial setting.

Caution1. Refer to “Common Safety Instructions for Fittings” for the safety instructions

for fitting part.

2. Instructions for Installing Controllers① Use proper tools to tighten a hexagonal-column or a knurling, when installing

the controller.

② Refer to the following table which shows the recommended tightening torqueto tighten thread. Excessive tightening may break the thread part or deformthe gasket to cause a fluid leakage. Tightening thread with the tighteningtorque lower than these limits may cause a loosened thread or a fluid leakage.

3. Instructions for removing Controller① When removing controllers, use proper tools to loosen a hexagonal-column or

a knurling.② Remove the sealant stuck on the mating equipment. The remained sealant

may get into the peripheral equipment and cause malfunctions.

4. Fixed Orifice Joint Series and Speed Controller Constant Flow Series havedeviation of flow rate. Contact us, in case a very accurate amount of flow rateis required.

5. If PISCO products generate heat by an adiabatic compression, totaltemperature including the heat from the product must be controlled within therange of the specification.
